The experiment was conducted during November, 2012 - March, 2013 at Regional Spices Research Centre, BARI, Joydebpur, Gazipur to develop onion variety (s) with respect to size, shape, pungency, keeping quality under ordinary storage condition and toleant to disease. The planting materials were BARI Piaz-1, BARI Piaz-4, BARI Piaz-5 and ON0064. The higher seed yield was obtained from BARI Onion-1 (30g) and BARI Onion-4 (30g) and the lower seed yield was obtained from BARI Onion-5 (10g). The seeds were stored for bulb production. The seeds were stored for bulb production.

Variety and Species
To develop high yielding variety (s) with desired pungency, keeping quality and tolerant to purple blotch disease from different crosses.
The trial was conducted during Rabi season of 2012-2013 at Regional Spices Research Centre, BARI, Joydebpur, Gazipur by using onion variety BARI Onion -1 (winter), BARI Onion -4 (winter), BARI Onion -5 (summer) and line ON0064 with no replication in a single row system maintaining distance of 50 cm from plant to plant. The crop was fertilized with N115P55K75S20Zn4B1.5Mo1kg/ha. The entire amount of cow dung P, S, B, Zn, Mo, ¼ N and ¼ K was applied during land preparation. The rest N was applied in three equal splits at 30, and 50 and 70 days after planting (DAP). The rest K was applied in three equal splits at 30, 50 and 70 DAP. Uniform sized (20g) bulbs were planted on November 03, 2012. Intercultural operations such as weeding, irrigation etc. were done as and when needed. As soon as the first flower opened, individual plots were netted for avoiding cross pollination. After bursting of umbel, the umbels within a net were rubbed each other for a couple of days to ensure self-pollination. Matured seeds of selected umbels were harvested on March 27, 2013
